[Help] Upgrading RAM: HP Compaq 8100 Elite SFF

[jhun1225]

So now, after my recent thread, my computer is working fine, I want to upgrade my RAM.

HP Compaq 8100 Elite SFF
Installed OS: Windows 7 Professional 64-bit

Installed RAM: 2x2GB
Brand Name: Kingston
Brand Code: KTH9600B/2G
Size: 2GB
Volts: 1.5V

Specifications:

DDR3 SDRAM PC3-10600
1333MHZ Non ECC 240-Pin

Can I use different brand but the same specifications together with the two old ram stick?

So it will be...
DIMM3: 2GB (Old)
DIMM4: 2GB (Old)
DIMM1: 4GB (New)
DIMM2: 4GB (New)

Total: 12GB RAM

Hope it will work.

@jhun1225,

1 and 3 should be black sockets.  Put the 4GB into those.    See manual page 3-4 and 4-5

Oh, thank you for your reply @wb2001.

I thought it would be that way.

Thank you for correcting me.

Can you explain it to me why would it be?

Here's my DIMM slot order:

DIMM3 (Black)

DIMM4 (White)

DIMM1 (Black)

DIMM2 (White)

In manual:

Memory Socket Loading

Channel A

Socket 1       Socket 2

Channel B

Socket 3      Socket 4

I'm still confuse about this.

Do every mobo dimm have different order of slots and channels?

@jhun1225,

The manual states color coded.

So after seeing again the system information under BIOS, I found out these configurations and you are correct @wb2001

Channel A

XMM1 2048MB / XMM2 2048 MB

Channel B

XMM3 2048 MB / XMM4 0 MB

I thought Black is Channel A and White is Channel B that's why I'm confused.

Thank you again @wb2001
